Abu Ali al-Hasan (Alhazen) (965-1039 AD) was a Muslim mathematician and astronomer born in Basra. He made numerous discoveries in optics, astronomy, and mathematics, and wrote commentaries on Aristotle, Ptolemy, and Euclid. He also wrote on methods of discovery.

Why is Alhazen considered the father of modern optics?

As stated above, he contradicted Ptolemy’s and Euclid’s theory of vision that objects are seen by rays of light emanating from the eyes; according to him the rays originate in the object of vision and not in the eye. Through these extensive researches on optics, he has been considered as the father of modern optics.

Who was Alhazen and what are his contributions to math?

He was the first to realize that a hypothesis needs to be tested through verifiable experiments or mathematical proof, thus developing the scientific method 200 years before it was adopted by European scientists.

The Arab scholar Ibn Al-Haytham (945–1040), also known as Alhazen, is generally credited as being the first person to study how we see. He invented the camera obscura, the precursor to the pinhole camera, to demonstrate how light can be used to project an image onto a flat surface.
 

What is the contribution of Al Rahwi in the evolution of scientific method?

Al-Rahwi (851 – 934) was the first scholar to use a recognizable peer review process. In his book, Ethics of the Physician, he developed peer review process to ensure that physicians documented their procedures and lay them open for scrutiny.

Who is the world’s first true scientist?

This is especially remarkable in light of the fact that most of his notions about the workings of the world were completely wrong. But in spite of this, Aristotle is widely regarded as the first real scientist.
 

Who is world No 1 physicist?

Albert Einstein



Three great theories define our physical knowledge of the universe: relativity, quantum mechanics and gravitation. The first is the handiwork of German-born Albert Einstein (1879-1955), who remains the physicist with the greatest reputation for originality of thought.
 

Who is father of science?

Galileo Galilei

Albert Einstein called Galileo the “father of modern science.” Galileo Galilei was born on February 15, 1564, in Pisa, Italy but lived in Florence, Italy for most of his childhood. His father was Vincenzo Galilei, an accomplished Florentine mathematician, and musician.
